Multiplexing generalized periodic Markovian sources with an application to the study of VBR video

Abstract

Presents a stochastic traffic model which is capable of capturing the time-scale dynamics associated with the potentially large disparity between source and output-link speeds in packet networks such as ATM. The model is applied to the study of variable bit rate (VBR) video sources in which cells are delivered at a sub-frame level referred to as a slice. A tractable analytical technique is presented for the study of a finite-capacity multiplexer under an input process determined by the superposition of N of the proposed traffic models.<>
